Intro

This is a Redis Cluster Controller to control the state of the cluster nodes and provide http api and tools(both command line and web ui).

It is production-ready and used at baidu.com, with a scale of 1500+ machines.

The system should be used conbining with https://github.com/ksarch-saas/redis and https://github.com/ksarch-saas/r3proxy:

Features

• Multi-IDC Support, every node has a tag, never elect node in a backup region as master.
• Replication via siblings, do partial resync from new master if it is our sibling.
• Builtin web console and command line tools for realtime monitor and control.
• Configurable read preferences, you can read from primary, primary_preferred or neareat region.
• Global failover constraint, if many many clusters deploy on the same machine pool, two clusters will never exec failover jobs at the same time.
• Slot rebalance.
• Cluster configuration convergence, topology of cluster maintained by redis cluster nodes
